Device for removing fused slags on slabs

A device for removing fused slags on slabs, characterized in that a <-shaped stationary front cutter shaping the front center thereof being the inlet side for a slab as the apex;

• middle cutters each consisting of a cutter part installing a spring disposed with a required spacing from said front cutter and lapping over with said front cutter and each stationary cutter part placed adjacent to the outside of said cutter part installing a spring;
• and rear cutters each consisting of a cutter part installing a spring disposed similarly to that of said middle cutters and lapping over with the stationary cutter part positioned before said cutter part one another and each stationary cutter part placed adjacent to the outside of said cutter part installing a spring are provided on a tool rest being vertically movable, respectively;
• and each projection level of the share point in a cutter part installing a spring is made to be somewhat higher than that of each stationary cutter part positioned before the very cutter part in order to cut out the fused slags on said slab in the transferring of the slab of a prescribed length.

A method for removing fused dross on slabs comprising subjecting a slab such as a continously cast slab or the like to continuous gas cutting on a hot slab transferring table;

• thereafter water-cooling a deposited portion of the fused dross on the undersurface of said slab in the cut-off portion thereof;
• adjusting a temperature at the end face of said slab in said deposited portion of the fused dross to 650.degree. C. or less;
• and then shearing and removing said fused dross.

A device for removing fused dross on slabs, characterized in that a gas cutting means for subjecting a slab such as a continuously cast slab or the like to continuous gas cutting on a hot slab transferring table line is followed by a shearing and removing means for cutting out the fused dross deposited on the undersurface of said slab in the cut-off portion thereof;

• and water-cooling means for water-cooling said deposited portion on the fused dross on said slab are disposed before and behind said shearing and removing means for fused dross, respectively;
• whereby said device is arranged such that said fused dross is sheared and removed by means of said shearing and removing means.
